Hmm, speculum access to the brain versus an increased intensity factor to a backrub?! This is indeed a challenge!

Interesting way to view it, @rngstgstll I was thinking of it as perpetually wearing a hat to hide my shame or risking my shirt ripping off and going flying across the room any time I thought of something arousing like The Incredibly Perverted Hulk. (I am not sure why, in my mind, the back penises have the power of super erections, because I am well aware that's not generally how erections work.)

Hmm, I guess I was thinking that maybe everyone else had the same choice, or that it was a group thing. Which leads to some interesting changes in the Kama Sutra I suppose ...

Even if everyone had the same choice, I am not sure if society would just allow us to all jam out with our clams out. Not at first anyhow...

Still, speculum access to the brain ... would make for some interesting potential (neural) hook-ups ...
